Log System Information to Console

Node.js

Technical Specification

Write a script that logs OS platform, total memory, free memory, and CPU count.

Input/Output Samples

Input:node sysinfo.js

Output:Platform: win32, CPUs: 8, ...

Optimal Logic Path

const os = require("os");

console.log("Platform:", os.platform());
console.log("Total memory (MB):", (os.totalmem() / 1024 / 1024).toFixed(0));
console.log("Free memory (MB):", (os.freemem() / 1024 / 1024).toFixed(0));
console.log("CPU cores:", os.cpus().length);

Architectural Deep-Dive

The os module exposes system-level info like memory and CPU which is useful for diagnostics.
